Tent camping near Vashon, Washington ranges across Puget Sound islands and mainland wilderness areas within 50 miles. Most sites experience fog and mist in early mornings throughout summer months, with average overnight temperatures dropping to the mid-50s even in July. The region's marine-influenced climate creates distinct camping conditions compared to other parts of Washington, with rainfall patterns that leave many campsites muddy in spring.
What to do
**Wildlife viewing: Early morning is prime time for spotting deer and birds at Hope Island Marine State Park Campground. "There is some wildlife on the island deer and birds," notes Rich M., who recommends kayaking from Arcadia Point to reach this boat-in destination.
Hiking on island trails: Explore 2 miles of trails at Hope Island where campers can circumnavigate the entire island in under 2 hours. Emma A. reports it's "a lovely boat-in campground" with "beautiful getaway" opportunities including "beaches, hiking trails and the chance to dig for clams in the right season."
Lake swimming: The crystalline waters at Mowich Lake Campground offer refreshing but cold swimming throughout summer. "The lake is this amazingly clear, turquoise blue. You can see the fallen dead wood sitting at the bottom of the lake," notes Maria P., who recommends visiting on weekdays to avoid crowds.
Fishing: Several campsites provide access to productive fishing spots, particularly at Lena Lake where trout are commonly caught during early morning hours. According to one visitor, they "saw fish surface for bugs on the lake as the sun went down" while camping at the lake.
What campers like
Solitude at off-peak times: Weekdays offer significantly less crowded camping experiences at most sites near Vashon. "Lower Lena Lake was in full on spring while upper Lena was still locked in the grip of winter," mentions Matthew G., highlighting the varied experiences at Lena Lake Campground throughout the seasons.
Marine views: Multiple boat-access sites provide unobstructed views of Puget Sound waters. At Blake Island Marine State Park Campground, Christi R. says it "is a peaceful getaway from the hustle and bustle with gorgeous views of the city. Hike the perimeter trail for views all around the island."
Multi-day hiking options: Several campgrounds serve as basemaps for extended hiking. According to Jess G., "If you don't make it to the upper lena lake, that's ok! Lena lake itself is just as beautiful on its own. You will need a parking pass if parking at trail head!"
Unique island camping: Boat-only access islands create distinctive camping experiences not found elsewhere in the region. Julia S. notes that at Blake Island, "Getting here by boat is about an hour from Seattle and there are volunteers that help at the dock."
What you should know
Temperature fluctuations: Many sites experience significant temperature drops after sunset, even in summer. At Mowich Lake Campground, one camper warns "Even in July there is snow and temperatures reached as low as 40F. Fortunately we were prepared, but you may not be."
Limited parking: Several popular tent camping areas have restricted parking that fills early. "We got there at like 3pm on a Tuesday and got one of the last 2 spots, it definitely fills up fast even during the week," reports Megan H. about Mowich Lake.
Bear safety: Multiple campgrounds require proper food storage due to active bear populations. Laura F. warns about Mowich Lake: "There are bears! Although I didn't see one apparently according to our neighbor he walked right behind me."
Boat access requirements: Several of the best tent camping spots near Vashon require watercraft to reach. Rich M. advises for Hope Island: "To access take Hwy 101 to Taylor Town and drive out to Arcadia Point. There is a gravel parking lot. Kayak the short jont east to the island."
Limited amenities: Most sites lack running water and have only basic facilities. Caren M. notes that Green Mountain "Has about 5 tent spots with picnic tables and fire pit. Had a bathroom but no other amenities- drinking water, shower, firewood/ice for sale."
Tips for camping with families
Beginner-friendly options: For families new to backcountry camping, certain sites offer gentler introductions. Matthew G. recommends "this hike for beginner and intermediate hikers as a potential introduction to the Olympic peninsula."
Quieter weekday visits: School-aged children will find more space to explore during weekdays when campgrounds see significantly less traffic. Jason H. mentions Lena Lake "offers fire rings and has plenty of amazing views of the lake. Don't forget to pack everything out and leave no trace."
Private camping alternatives: Families seeking more privacy can consider Malaney Creek Farm, where TJ J. describes: "our spot was the Trillium site which has a few hundred foot hike from where you park your car and the portable toilet. the site was pretty cool and very secluded."
Educational opportunities: Several campgrounds offer natural learning experiences. TJ J. noted at Malaney Creek Farm: "there is a camp box with info, instant coffee, guides to area sight seeing and food along with a log book to write about your stay."
Tips from RVers
Limited RV options: Most of the best tent camping near Vashon lacks facilities for larger RVs. Ivy K. notes that Green Mountain has "nice clean camping area with easy access to multiple trails and logging roads. Trails are open to hiking horseback riding and motorcycles."
Road conditions: Access roads to several campgrounds present challenges for RVs. Megan H. warns about Mowich Lake: "the gravel road to get up there, it's like 15 miles long and it's rough. Not the worst road I've ever been on but it wasn't fun and it felt like you had to drive it forever."
Alternative setups: Some sites accommodate small camper vans with prepared tent platforms. At Mowich Lake, Jessie T. notes "designated box type platforms for the tents" but warns "cars have to be parked away from the campsite."
